Is a main contractor liable for a subcontractor in the UK?

Not automatically. A main contractor is not always liable simply because a subcontractor caused a problem. However, liability may still arise depending on the contract, the nature of the work, the level of control, the duties owed and how the arrangement operated in practice.

Can a customer sue the contractor for work done by a subcontractor?

Yes, they may try to. If the customer contracted with the main contractor, they may argue that the main contractor remains responsible for delivering the agreed service. The main contractor may then need to consider whether it has a separate claim against the subcontractor.

What is the difference between a subcontractor and an independent contractor?

A subcontractor usually performs part of a larger contract for another contractor. An independent contractor usually provides services on their own account. In practice, the terms can overlap. What matters is the real relationship, not just the label used in the agreement.

Are employers liable for independent contractors?

Usually, a business is less likely to be liable for a genuinely independent contractor than for an employee. But the risk depends on the facts. If the business controls the work closely or the relationship looks similar to employment, liability arguments may still arise.

How can a business protect itself when using subcontractors?

Use clear written contracts, require suitable insurance, define responsibility for defects and complaints, include indemnity clauses where appropriate, keep evidence of independence, and avoid exercising unnecessary control over how the subcontractor performs the work.
